Proton Exchange Membrane Electrolyzer Coating – Ultrasonic Coating – Cheersonic
Proton exchange membrane electrolyzer catalyst layer coating devices have wide applications in multiple fields. The following is a detailed description of their application areas:
Hydrogen Energy Field
Proton exchange membrane electrolyzers (PEMECs) are one of the key technologies in the hydrogen energy field, used to decompose water into hydrogen and oxygen, providing a new route for hydrogen production. The catalyst layer coating device plays a crucial role in the PEMEC preparation process, ensuring that the catalyst is uniformly coated on the proton exchange membrane, thereby improving electrolysis efficiency and hydrogen purity. This technology provides strong support for hydrogen energy production and storage, promoting the development of the hydrogen energy industry.
Fuel Cell Field
Proton exchange membrane fuel cells (PEMFCs) are energy conversion devices that convert the chemical energy stored in hydrogen into electrical energy through electrochemical reactions. The catalyst layer coating device is also crucial in the PEMFC membrane electrode preparation process. By precisely controlling the coating parameters, a catalyst layer with high power density, low platinum loading, and good durability can be obtained, thereby improving the performance and lifespan of the PEMFC. PEMFCs (Proton Exchange Membrane Electrolytes) possess advantages such as high efficiency, environmental friendliness, and zero emissions, and have broad application prospects in fields such as new energy vehicles and distributed energy systems.
Energy Storage
Proton exchange membrane electrolysis technology can also convert electrical energy into chemical energy, storing hydrogen in high-pressure hydrogen storage tanks for later use. This technology has wide applications in the energy storage field, providing strong support for renewable energy storage and peak shaving. The catalyst coating device also plays a crucial role in this process, ensuring uniform catalyst distribution during electrolysis, thereby improving energy storage efficiency and stability.
Other Fields
Besides the above-mentioned fields, the catalyst coating device for proton exchange membrane electrolyzers can also be applied to other fields requiring efficient and environmentally friendly electrochemical technologies, such as environmental protection and chemical engineering. In these fields, the catalyst coating device also plays a vital role, promoting the development and application of related technologies.
Ultrasonic spray coating machine for proton exchange membrane electrolytic cell coating
Ultrasonic spraying machine is the core equipment for coating preparation of proton exchange membrane (PEM) electrolyzer. Relying on high-frequency ultrasonic atomization technology, it can accurately deposit uniform and dense catalytic coatings on the surface of proton exchange membrane, and is suitable for noble metal catalyst slurries such as anode IrO ₂/RuO ₂ and cathode Pt/C.
When spraying, the 20-120kHz high-frequency vibration atomizes the slurry into uniform droplets of 20-50 μ m, and non-contact deposition avoids membrane swelling, wrinkling, or damage, perfectly adapting to ultra-thin proton membranes of 30-50 μ m. The coating thickness can be accurately controlled within 0.1-5 μ m, with a thickness deviation of ≤± 2%, completely solving the defects of pinholes and uneven thickness in traditional processes.
The catalyst utilization rate of this technology is as high as 85% -95%, significantly reducing the loss of precious metals such as platinum and iridium and lowering costs. The uniform catalytic layer can construct a stable gas liquid solid three-phase interface, reduce the overpotential of hydrogen/oxygen evolution reactions by 10% -15%, improve proton conduction efficiency by 15% -20%, enhance membrane chemical stability, and extend the service life of the electrolytic cell.
